CHARLES E. TROWVBRIDGE, OF VVHITINSVILLE, MASSACHUSETTS, ASSIGNOR TO THE WVHITINSVILLE SPINNING RING COMPANY, OF SAME PLACE.

APPARATUS FOR BURNISHHNG SPlNNlNG RlNGS,

SPECIFICATION forming part of Letters Patent No. 391,725, dated October 23, 1888. Application filed July 28, IRSB. Serial No. 281,275. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES E. TROW- BRIDGE, of Whitinsville, county of WVorcester, State of Massachusetts, have invented an Iu1- provement in Apparatus for Burnishing Spinhing-Rings, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

In ring-spinning frames the inner flange of the race of the ring when first put into use quickly wears and cuts into the traveler, destroyingit, and this wear continues until finally by the employment of several travelers the inner flange of the race is worn smooth. To lessen this rapid wear of and thereby save a great number of travelers, I have made numerous experiments, all aiming to devise some method or operation whereby the inner flange of the traveler-race might be quickly and practically smoothed or polished, and as a result of my experiments I have ascertained that a spindle or shaft having combined with it arms or appliances of such construction as to expand or throw out under centrifugal action against the interior of the said flange may be most successfully employed for such purpose. I have also provided means whereby a number of rings may be held and operated upon at the same time, and to facilitate the operation of the parts the relative longitudinal positions of the ring and spindle or shaft may be changed from time to time, and so, also, the case containing the rings may be rotated, if desired.

In the embodiment of the invention herein contained I employ a vertical spindle having a series of arms, and the ring case or receiver is moved vertically by a rail, like the usual ringrail of a ring-spinning frame.

This invention consists, essentially, in a case or receiver to hold one or more rings, combined with a rotary spindle or shaft having centrifugal arms or appliances to strike against and polish or smooth the inner flanges of the U ring or rings,substantially as will be described.

Other features of my invention will be pointed out in the claims at the end of this specification.

Figure l is a front View of enough of the right-hand end of a machine for polishing the flanges of spinning-rings to enable my invention to be understood; Fig. 2, a section in the line as, looking to the right; Fig. 3, an enlarged vertical section in the line 00' through the case and rings, the spindle being in elevation and supposed to be standing still, the dotted lines showing the worm; Fig. 4, a detail showing one set of arms and their holder, and Fig. 5 shows a plan and edge view of a washer.

The frame A, step-rail A, steps A main 6c shaft B, cylinder 13, and band B extended from it to [he whirl of the spindle, and the bolster and lifting-rails O O are and may be all as common to spinning or twisting frames using rings, the said rail in operation being reciprocated vertically, as in ring-spinning frames, and by any devices usual in that class of machine.

The spindle D, as herein shown, is reduced at its upper end for the reception of a series of holders, a, shown separately in Fig. 4E, and preferably formed of wire, or they may be cut out of sheet metal, and to these holders are loosely pivoted a series of arms, a. A number of these holders are applied to the spindle 7 5 and retained there by a nut, D, thus making one form of spindle, or it may be shaft, having arms or appliances which, when the spindle or shaft is rotated rapidly, are thrown out or made to expand, owing to centrifugal action, and made to strike and rub against the inner flanges, 2, of the rings 0', a series of which are held in the case or receiver E. This case or receiver is made as a cylinder, which takes a bearing in a plate, 8, which in practice will rest on the usual rail, 0. The ends of the case are closed by heads 0 0, preferably made as screw-caps having central openings just a little larger in diameter than the inner diameter of the rings, so as to act against the rings and or: keep them in the case or receiver.

I have shown the case as provided with a wormgear, (Z, which may be engaged by a worm, d, on a shaft, 6?, supported in bearings d on the rail 0, the said shaft having on it a bevel-gear, d, which is engaged with and rotated by a bevel-gear, (2 mounted loosely in bearings in the rail and splined to the vertical and provided engaged by a bevel-gear, Ioo

shaft 01, having bearings at d d with a bevel-gear, d,

b, on a shaft, b, provided with a bevel-gear, b, engaged by a bevel-gear, b fast on the main shaft B. If desired, the gearing between the gear I) and worm-gear d may be omitted in case it be not desired to rotate the case or receiver E.

When the spindle D is rotated rapidly, its arms a fly outward, as shown by dotted lines, Fig. 3, wherein some of the arms are shown as extended, the said arms contacting with or hitting against or striking the flanges 2 and ring 1, thus wearing the same smooth, so that the flange 2, when the ring is put into use,will not wear and cut into the traveler, as heretofore.

The holders (6 on the spindle are separated by washers h. (See Fig. 5.) Byjointing or pivoting the arms a to the spindle it is possible to polish the flanges of rings of different diameter, a case of suitable diameter being employed suitable for the diameter of the rings to be acted upon.

Believing myself to be the first to polish or smooth the inner flanges of rings by centrifugally-acting arms or devices connected to a rapidly-rotated spindle or shaft, I do not desire to limit my invention to the exact form of device used to contact with the flanges 2, as other forms of devices could be readily employed, which, when the spindle is rotated, will be made to rub against the flanges. The rail 0 is mounted upon usual lifting-rods, 0, whereby it may be reciprocated, as common in ring-spinning frames.

I have in the drawings shown one form or train of mechanism for rotating the holder for the rings when desired; but if the holder is to be rotated I may employ for such purposes any usual contrivances such as employed in spinning-frames for rotating spindles.

I claim- 1. A case or receiver to hold one or more rings, combined with a rotary spindle or shaft having centrifugal arms or appliances to strike against and polish orsmooth the inner flanges of the ring or rings, substantially as described.

2. A case or receiver having open heads to receive between them and hold a series of rings, combined with a spindle or shaft having holders and arms a, pivoted thereto and adapted to be thrown out by centrifugal ac tion against and to strike the rings, substantially as described.

3. The rail 0, the ease or receiver, and the spindle or shaft having centrifugal arms or appliances to strike against the inner flange of the race of the ring, combined with means to rotate the spindle or shaft and to change the positions longitudinally with relation to each other of the case or receiver and spindle or shaft, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
